Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically a filter structure for exhaust gas treatment equipment. Background Technology

[0002] Existing exhaust gas treatment equipment usually has a filter device installed to filter and adsorb large particulate impurities. In order to facilitate disassembly and maintenance, some exhaust gas treatment equipment uses a plug-in mechanism and a limiting mechanism to remove and install the filter screen. For example, Chinese utility model patent with announcement number CN221195164U discloses an environmentally friendly filter structure for exhaust gas treatment equipment.

[0003] However, in actual use, it is found that after a long period of use, particulate matter or pollutants accumulate on the surface of the filter media, gradually clogging the pores, which leads to increased airflow resistance and reduced filtration efficiency. If the machine is stopped to disassemble the filter for cleaning or to replace the filter element, it will increase labor, consumable and time costs. Utility Model Content

[0004] The purpose of this invention is to provide a filter structure for exhaust gas treatment equipment, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter structure for exhaust gas treatment equipment, including a dustproof mounting frame, wherein a plurality of dustproof filters are installed inside the dustproof mounting frame, each dustproof filter is provided with a cleaning component on its side, and a collection component is provided below each dustproof filter, and a lifting component is provided on the side of the dustproof mounting frame, the lifting component being connected to the cleaning component.

[0006] The cleaning assembly includes a cleaning plate and a connecting rod fixed above the cleaning plate. The cleaning plate has bristles that contact the dust filter, and the connecting rod passes through the top of the dustproof mounting frame. The dust filter can be cleaned by moving the cleaning plate up and down. The cleaning assembly is located on both sides of the dust filter and will not affect the subsequent disassembly and maintenance of the dust filter.

[0007] The lifting assembly includes a slide rail, a lead screw, a slider, a drive motor, an L-shaped plate, and a connecting frame. The slide rail is fixed to the dustproof mounting frame. The lead screw is rotatably connected inside the slide rail, and the slider is threaded onto the lead screw. The drive motor is fixed to the end of the slide rail, and its drive shaft is connected to the lead screw. The connecting frame is located above the dustproof mounting frame. Both ends of the L-shaped plate are fixed to the connecting frame and the slider, respectively, and the top of the connecting rod is fixed to the connecting frame. The drive motor drives the lead screw to rotate, causing the lead screw to drive the slider to move up and down. This causes the slider to move the connecting frame via the L-shaped plate, thereby driving the cleaning assembly to clean the dustproof filter.

[0008] In a preferred embodiment of this invention, the slider is fitted against the inner wall of the slide rail, and a sliding connection is used between the slider and the slide rail. This restricts the slider and improves its stability during movement.

[0009] In a preferred embodiment of this invention, the L-shaped plate is fixed to the slider and connecting frame by bolts. This facilitates subsequent disassembly and maintenance.

[0010] In a preferred embodiment of this invention, the collection component includes a sinking trough and a pull-out frame. The sinking trough is located below the dustproof mounting frame, and the pull-out frame is inserted into the sinking trough. Clean, large particles of impurities fall into the pull-out frame and are collected for easy processing.

[0011] As a preferred embodiment of this utility model, mounting plates are fixed at both ends of the dustproof mounting frame, and the mounting plates are mainly used to fix the device on the exhaust gas treatment equipment.

[0012] As a preferred embodiment of this utility model, a handle is fixed to the end of the pull-out frame, and the handle is mainly for the convenience of operating the pull-out frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention achieves full-coverage cleaning of the filter screen through motor drive, eliminating the need to stop the machine to disassemble the filter screen and significantly reducing manual maintenance costs. A single motor drives all cleaning plates in tandem, completing the cleaning of multiple filter screens in one operation. Slide rails limit the sliders to prevent wobbling during cleaning, ensuring that the cleaning plates apply force vertically. Attached Figure Description

[0024] Please see Figure 1-5 This utility model provides a technical solution: a filter structure for exhaust gas treatment equipment, including a dustproof mounting frame 1. Several dustproof filter screens 2 are installed inside the dustproof mounting frame 1. Each dustproof filter screen 2 has a cleaning component 3 on its side, and a collection component 5 is located below each dustproof filter screen 2. A lifting component 4 is located on the side of the dustproof mounting frame 1, and the lifting component 4 is connected to the cleaning component 3. The dustproof filter screens 2 and the dustproof mounting frame are detachably installed.

[0025] The cleaning assembly 3 includes a cleaning plate 301 and a connecting rod 302 fixed above the cleaning plate 301. The cleaning plate 301 is provided with bristles that contact the dust filter 2. The connecting rod 302 passes through the top of the dustproof mounting frame 1. The dust filter 2 can be cleaned by moving the cleaning plate 301 up and down. The bristles are made of polyphenylene sulfide, polyimide, polyetheretherketone, PTFE, or metal wire to improve high-temperature resistance and corrosion resistance.

[0026] The lifting assembly 4 includes a slide rail 401, a lead screw 402, a slider 403, a drive motor 404, an L-shaped plate 405, and a connecting frame 406. The slide rail 401 is fixed to the dustproof mounting frame 1. The lead screw 402 is rotatably connected inside the slide rail 401. The slider 403 is threadedly connected to the lead screw 402. The drive motor 404 is fixed to the end of the slide rail 401, and the drive shaft of the drive motor 404 is connected to the lead screw 402. The connecting frame 406 is located above the dustproof mounting frame 1. The two ends of the L-shaped plate 405 are fixed to the connecting frame 406 and the slider 403, respectively, and the top end of the connecting rod 302 is fixed to the connecting frame 406.

[0027] The drive motor 404 drives the lead screw 402 to rotate, which in turn drives the slider 403 to move up and down. The slider 403 then drives the connecting frame 406 to move via the L-shaped plate 405, thereby driving the cleaning component 3 to clean the dust filter 2.

[0028] Furthermore, the slider 403 is fitted against the inner wall of the slide rail 401, and a sliding connection is adopted between the slider 403 and the slide rail 401. This restricts the slider 403 and improves the stability of the slider 403 during movement.

[0029] Furthermore, the L-shaped plate 405 is fixed to the slider 403 and the connecting bracket 406 by bolts. This facilitates subsequent disassembly and maintenance.

[0030] Furthermore, the collection component 5 includes a sink trough 501 and a pull-out frame 502. The sink trough 501 is located below the dustproof mounting frame 1, and the pull-out frame 502 is inserted into the sink trough 501. The sink trough 501 and the pull-out frame 502 are detachably installed. A sealing gasket is used between the sink trough 501 and the pull-out frame 502 to improve the sealing performance, and large clean particles of impurities fall into the pull-out frame 502 for collection and processing.

[0031] Furthermore, mounting plates 101 are fixed at both ends of the dustproof mounting frame 1. The mounting plates 101 are mainly used to fix the device to the exhaust gas treatment equipment.

[0032] Furthermore, a handle is fixed to the end of the pull-out frame 502, and the handle is mainly for the convenience of operating the pull-out frame 502.

[0033] In summary, when using this device, starting the drive motor 404 causes the lead screw 402 to rotate, and the threaded slider 403 moves up and down along the slide rail 401. The slider 403 pushes the connecting frame 406 through the L-shaped plate 405, and the connecting frame 406 drives the connecting rods 302 of all cleaning plates 301 to move synchronously. The bristles on the cleaning plates 301 scrape the surface of the dust filter 2 as they move up and down, removing accumulated dust. Large particles of impurities that are cleaned and detached fall due to gravity and enter the sink trough 501 at the bottom of the dustproof mounting frame 1. The impurities are collected by the pull-out frame 502, and can be manually pulled out for disposal when the trough is full.

[0034] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
